Alignment and sequencing errors are a major concern in molecular evolution, and this valuable study represents a welcome improvement for genome-wide scans of positive selection. This new method seems ...

Dogs have lived with Indigenous Americans since before they came to the continent together 10,000 years ago. A new analysis ...

One study is of enamel proteins from extinct mammal fossils from the Turkana Basin in Kenya, and the other study is of enamel proteins from extinct mammals in the Haughton impact crater site located ...

Sharks are, by any definition, incredibly badass. They’re the only animals around that can claim to have chowed down on honest-to-goodness dinosaurs; they induce what is genuinely known to biologists ...

Vessels in a tree’s xylem transport water from the roots to the rest of the plant. Hardwood tree species tend to have large ...

Examples of the rarest variety in the town, the Kentucky coffee tree, are planted on Princeton Boulevard, according to town forestry division foreman David DiNatale.

From pollinating plants to dispersing seeds, birds play a variety of crucial roles that help to keep ecosystems in balance. But when we degrade and fragment their habitats, some species disappear much ...

For example, does belowground mutualism govern patterns beyond tree species diversity? How much of the carbon that forests sequester at the surface can be attributed to underground activity? "And what ...
